Trachyonychia means rough, longitudinally ridged nails with a sandy, brittle and thin aspect. It is a rare condition that occurs mainly in children. Studies on trachyonychia are rare. We aimed to describe the clinical aspects and outcome of trachyonychia, as well as its treatment.
Two boys aged 11 and 14 years old and a girl aged 6 years presented with nail dystrophy of the fingers and toes. Patient 1 had also a scaly patch on the glans penis, and patient 2 was atopic. Trachyonychia associated with psoriasis was suspected in patient 1 and the idiopathic form was retained in the other two patients. All patients were treated with topical steroids for a few months. The patients did not show any improvement at the six-month follow-up. Only one patient was contacted again after two years and showed spontaneous healing.
The diagnosis of trachyonychia is mainly clinical. In the literature, 62% of pediatric patients had an idiopathic form. However, a strong association was observed between trachyonychia and alopecia areata. Trachyonychia of childhood appears to have a good prognosis, with spontaneous improvement within six months to two years. Therapeutic abstention is the rule.
糙甲症是指指甲粗糙、有纵向嵴，外观呈沙质、易碎且薄。这是一种主要发生在儿童中的罕见病症。关于糙甲症的研究很少。我们旨在描述糙甲症的临床特征、预后及其治疗方法。
两名11岁和14岁的男孩以及一名6岁的女孩出现手指和脚趾甲营养不良。患者1阴茎头有鳞屑斑，患者2有特应性体质。患者1怀疑为与银屑病相关的糙甲症，另外两名患者诊断为特发性糙甲症。所有患者均接受了数月的外用类固醇治疗。在六个月的随访中，患者均未显示出任何改善。两年后仅与一名患者再次联系，其显示病情自愈。
糙甲症的诊断主要依靠临床。文献中，62%的儿科患者为特发性形式。然而，观察到糙甲症与斑秃之间存在密切关联。儿童期糙甲症似乎预后良好，在六个月至两年内可自发改善。通常采取不进行治疗的原则。
